Radar estimates indicate approximately 3.5 inches of rain fell on the Decatur area on Sunday. The torrential rainfall led to multiple reports of flash flooding and damage to homes and businesses in the area.

Some business owners said the city needs to address the poor drainage in the flood-prone areas they reside, before the losses take their toll.

Brad Smith's carpet store sustained heavy water damage. He suspects approximately $100,000 worth of damage was left behind.

"This is my life; the whole family is involved in the business," Smith said. "This is our livelihood. It's tough to see it underwater."

Smith said the store only just recovered from a storm last year, again sustaining heavy losses. He said he complained to the city council about the lack of drainage in the area, believing it to be in dire need of attention.

"I know it may be a small segment of the city to them, but it's our whole life," he said. "I think they're trying to make the old drains accommodate a lot of new development; that's just diverting water where it can't run off."

Candy shop owner Nancy Curl agrees that the area is in bad shape and that the city needs to address the drainage system.

"I would rather be making candy than worrying about wet cardboard and mold," she said. "This is just something that we cannot stand."
